Authorities on Thursday pleaded with a Wisconsin man who they say burglarized a gun store and made anti-religious and anti-government statements to turn himself in, and they urged residents to be extra vigilant during the holy weekend.

"The good thing is he has not hurt anyone," Rock County Sheriff Robert Spoden said. "We understand he has grievences. ... We encourage him to turn himself into the authorities. We are more than willing to discuss those what those grievances are, but he has to do the right thing come forward. We don't want people to get hurt, and we don't want him to get hurt."

Spoden said he doesn't have information or evidence that anyone is assisting Jakubowski in hiding from authorities, but "if they are, they're putting themselves at risk."

Janesville police Chief David Moore said Jakubowski was researching "survivalist" tactics prior to disappearing with the stolen guns and ammunition.

While portions of the 161-page manifesto authorities say he mailed to the president have been leaked to the media, Rock County authorities said it's still be analyzed and they're not releasing it.

Officials say Jakubowski is to be considered armed and dangerous. He is 32 years old and stands 5 feet, 10 inches tall and has green eyes and brown hair.

Anyone with information about Jakubowski's whereabouts is asked to call the Rock County Sheriff's Office at 608-757-7911 or the FBI at 800-CALL-FBI.

There is a $20,000 reward for information that leads to Jakubowski's arrest.
